Specification of Letters Patent No. 8,788, dated March 9, 1852.

Be it known that I, WILLIAM LINSLEY, of the township of l Vaddam, in the county of Stephenson and State of Illinois, have invented a new and useful Improvement in Machines for ShellingCorn, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, which forms partof this specification, and in which Figure 1 is a view in perspective of my improved corn sheller. Fig. 2 is a transverse section of the same, and Fig. 3 is an elevation of one of the springs of theshelling disk.

The. object of my invention is to shell ears of corn of varying size and shape, and it consists of a combination of stationary sectional spring shelling plates with a rotating sectional spring shelling disk; the two acting in such manner that they yield to thick ears of corn orto the thick part of an. ear and thus shell off the grain without breaking up the cob, while they close upon small ears or upon the small end of a thick ear and insure the separation of the grain from I the cob whatever may be its size and proportions. p In the machine represented in the accom panying drawing A is the frame which supports four corner standards, I), b, b b, and two middle standards cl cl. The corner standards 6 b, b b, are arranged in pairs, and the opposite standards of each pair are connected by transverse bars, 0 c, on which the two sets of shelling plates E E, are supported. Each setof shelling plates is composed of three sections 6, f, g, the uppermost, of which is flared outward to form a sort of hopper to receive the ears of corn. These sections arestudded with teeth 71; and each is pressed toward the center of the machine until it meets a stop by a separate spring j, whose extremities bear upon the outer side of the section and whose middle is made fast to the adjacent middle standard. These sets of stationary sectional yielding shelling plates face each other and the rotating shelling disk K is arranged to revolve between them. The disk is formed of two sections m, n, which are set back to back upon a transverse shaft L. The two sections are pressed apart from each other and of these sections are studded with teeth 0 which project toward the adjacent teeth on the stationary shelling plates, but are prevented from being forced into contact therewith by the action of the spring by stops on the shaft L. The periphery of the sectional disk is encircled by a case, which is not shown in the drawing to prevent the e11- trance of ears of corn between the two sections.

l/Vhen this machine is to be put to work the sectional shelling disk is caused to revolve rapidly by turning its shaft, which turning may be conveniently effected by means of a driving belt applied to a belt pulley secured to the shaft, or in any other convenient manner. The cars of corn are then thrown pro-miscuously into the open top of the machine and are drawn downward and shelled by the rotation of the disk acting in connection with the stationary shelling plates.

From the foregoing description it is evident that the sections of the rotating disk will yield in any direction to permit an ear of large size to pass through, and that the sections of the stationary plates will also yield to assist their action; while as smaller ears resent themselves the sect-ions of the rotatmgdisk and stationary plates converge under the action of their respective springs. The machine thus adapts itself to the varying circumstances which occur and the shelling of the grain is not only performed in a thorough and efiicient manner but the op eration is effected with great speed. The two parts of the disk may be pressed apart by spiral or other springs instead of the star shaped spring, and the machine may be variously modified in othersof its details, as may be deemed expedient by difierent constructors.

What I claim as my invention and desire to secure by Letters Patent is' The combination of stationary sectional spring shelling plates with a rotatingsectiona-l spring shelling disksubstantially in the manner herein set forth, the plates and disks having a wabbling or universal motion caused by the constant Varying of the space In testimony whereof I have hereunto between them to accommodate itself at the subscribed my name. same time to ears of varying size andshape,

by Which means the cobs are less bro-ken and WILLIAM LINSLEY' 5 more thoroughly stripped than in machines Witnesses:
